Dear NCL,
Adam, thanks,,
I tried to do it again as your suggestion. The plot is attached,
I think I still have a problem, as you can see where the bar charts are
still overlapped, is there any trick
how to manage this, at least to shift the overlapping bar?
I am really sure, this issue comes from the pdfx function, where the "bin
centers" are different from these
3 distribution, is there any way around how to solve this proble, I just
want at least get the bar attached one to another.
Thanks for your help. Regards.
